Verdicts

Acuity Scheduling API

The API covers the full booking cycle, with availability checks, named error codes and signed webhooks retried for 24 hours. API access is sold only on the Premium plan at $61 a month, the single OAuth scope grants the whole account, and no changelog, idempotency key or audit log was found in the reviewed documentation.

Zoom Scheduler API

Each of the 24 operations has its own granular OAuth scope, and Zoom Scheduler and the REST API are separate components on the status page. No operation moves a booking, no official SDK covers Scheduler, and Zoom's API terms forbid benchmarking or monitoring the service.

Before you call either

Acuity Scheduling API

  1. Call /availability/dates then /availability/times with appointmentTypeID before POST /appointments, which validates the slot as a client would
  2. Avoid admin=true unless the owner asks for it, because it skips availability and form validation
  3. Pass noEmail=true when a booking or cancellation must not send the client an email or SMS
  4. Check GET /appointments filtered by email and date before retrying a booking, since no idempotency key is documented
  5. Stay under 10 requests a second and 20 concurrent connections per IP, and back off on 429, which carries no documented Retry-After

Zoom Scheduler API

  1. Call GET /scheduler/schedules/{scheduleId}/available_times and book only a spot whose status is available
  2. Send start_date_time in ISO 8601 with the booker's IANA time_zone to POST /scheduler/attendee. Expect 409 on a conflict
  3. To move a booking, cancel it with PATCH /scheduler/events/{eventId} and status set to cancelled, then book the new slot
  4. List scheduled events before retrying a booking, because no idempotency key is documented
  5. Request a new Server-to-Server OAuth token every hour. That grant issues no refresh token
